Duber,


A single 3,000 Li-Po will power both engines' ignition systems, like a 1,500 Li-Po will power that of one engine...

I suppose a 'single point of failure' in a remotely operated plane may not be as great a disadvantage, as it is on a piloted plane.

A plane flown by a pilot is usually capable of 'limping home', if one engine fails...

But an R/C plane is, for most pilots, easier to bring home for a 'dead stick' landing (even a very remote one) than it is to be controlled with one engine out...


SPOF is usually a disadvantage in other circumstances.

Current draw for each ignition at top rpm of 6500 is about 650 mA.
With the single 1500 mAh battery you so have about one hour flight time in your twin engine plane.
